If the measurements are not wrong (which, geometry says they are in my mind), then you need to account for the gap between the 6.333 and the 7.5 measurement (1.17' * 13.583)... Don't see how it can be 33.333 on each side of the rectangle, but have 6.333 and 7.5 offsets.
13.583 * 1.17 = 8.867


1270.321 - 8.867 = 1261.454


What am I missing? Its just a simple box.
Just think of a birds eye view sketch of a pyramid, where you have all the measurements of the eaves (base) and all the hips (ridges) going to the top. You couldn't just take the b x h of the perimeter measurements for the total area. You'd have to measure the area of each triangle individually, then add them together.
